Abstract
Sonogashira coupling of 7-iodobenzotriazole derivative 9 with propargy lic alcohols followed by alkyne reduction leads to alkanols 11 or alka nols 12 which cyclize upon benzyne generation to give the iodo-chroman es 14 and iodo-chromenes 16. (C) 1998 Elsevier Science Ltd. All rights reserved.
